Two things: I would explain what U means in interval notation, and I would make the graphs easier to read. Also, specify how many decimal places to take the answers. The AP exam standard is 3.

This review of the ideas of Precalculus is very organized, and is explained in such a way that makes understanding it a trivial matter. I certainly hope the rest of this course is this good, kudos to whoever designed this.
I have only two complaints. First, add more questions throughout the lesson, with some challenging ones to keep everyone occupied untill the subject matter can be fully understood.
Second, make some of the graphins a little larger. I had trouble answer some of the questions with graphs in them.
Other than that, this is a good course, and I hope that I shall learn something from it
